Whitacker Police Chief John Vargo said he was forced to return confiscated guns to Michael Robinson after the District Attorney's Office withdrew firearms charges against Robinson.

"I returned two guns to Robinson, then a few weeks later, he shot people," Vargo said.

Vargo said the D.A.'s office dismissed or withdrew all the cases that Whitacker Police Officer William Davis was involved in.

Vargo said he has been forced to return all the evidence in those cases.

"I returned money and items to drug dealers we confiscated from a search warrant," Vargo said.

Davis is charged with official oppression and perjury in two separate cases.

Duquesne Law Professor Wes Oliver said the cases that were withdrawn could have been delayed.

"I think the fact that they dismissed them rather than delayed them is a pretty strong signal that the D.A's office believes this officer is not going to be credible at all when he testifies," Oliver said.

Davis said he is innocent and Vargo stands behind him.

"When it becomes a danger to the community, it makes you angry," Vargo said
